ASSEMBLY JIG FOR ELECTEOLYSIS LOVE

The invention relates to devices; which are used in the "I / iontage of IIile-tctrolysuren, and more precisely on ... 'ontagelehre for electrolysers, which - are intended for the exact placement of the centering pin on the plates of the electrolyser and the" iontag stands for the assembly of liatoden bells and diaphragms.

Ss teachings are known, the plate-shaped 'component with Includes openings for the elements to be centered (anodes, cathodes). When assembling the ul ect ro Iy se ure several are grounded such teachings are used.

The assembly of entire series of electrolysers remains very icompli ed even when using these gauges and requires high accuracy when installing the electrolyser. Therefore the assembly is very time-consuming and labor-consuming. As a result, who & ei jAontaj-je- and operating the electrolysers are expensive. The use of gauges in the assembly of the electrolyzer does not practically allow the Hetz to be installed precisely in the interelectrode space. Insüosun.,. Ore this is difficult when changing the bell without hurrying when the latter is immersed in the melt. If the diaphragm is mounted under an elec trolytschiciit, its position cannot be controlled and, above all, cannot be improved with such an excellent accuracy that a stable EIeJs-

trolysis process is guaranteed. Therefore, assembly of the electrolysers requires the use of known teachings high manufacturing accuracy of the electrolyzer parts, ■ for example the jackets, which are used as starting elements for centering to serve. If the diaphragm is not arranged concentrically in the interelectrode space, the electrical Current is unevenly distributed and this in turn has the consequence fc (e.g. in the production of metallic sodium) that calcium is deposited on the cathode and that calcium bridges are formed between the cathode and the diaphragm, as a result of which the current yield is greatly reduced.

It is the aim of the present invention to provide the elimination of the disadvantages.

The invention is based on the object of a teaching

the
and supports provided with screws on which the frame of the cathode bell rests. The contact block 11 of the anode is placed on the foundation 10 (FIG. 5a) and the electrolyzer jacket 12 is lowered from above, to which the supports (FIG. 5b) are attached. The cathode 8 (FIG. 5c) is placed on this and aligned with the aid of the screws 14 (FIG. 5b) so that its working surface is vertical. Starting from the cathode 8, the anode 15 (FIG. 4) is mounted and potted in the contact block 11 by means of lead 16.

Thereafter, the electrolyzer jacket 12 is lined with heat-resistant bricks and the lead-ins for the power supply lines are cast with heat-resistant concrete. The electrolyzer is then covered with plate 17.

After the electrolyzer tank has been installed, the Centering the electrolyzer with the mounting block for assembling the bell is tackled, resulting in the following Manner is carried out;

On the shoes 9 (Fig. 3) of the cylinder Ϊ8 (Fig. 5d) of the assembly block for assembling the bell 19 (Fig.5e) and the network element 5 (Fig. 3) is placed so that ee

1 0 9 8 1 7/0 7 U

is held by flange 7 on the shoes 9 and this touches with its inner surface.

Here, component 1 rests on reinforced concrete slab 17 which is supported by supports 20 (FIG. 5d).

Then centering pins 3 are inserted into the bores 2 (FIG. 4) of the teaching and on the metallic insert plates the plate 17 is welded. The gauge is then pulled out of the mounting block.

In this way the centering pins will look on the assembly arranged during assembly and during operation their situation will be checked from time to time.

With the help of the same teaching, the centering pins are opened attached to every electrolyser. For this purpose, the Teaching (Fig. 5f) used in the electrolyzer that the cylindrical gauge part enters the cathode 8 (Fig. 4 and 5g) and flange 7 on the upper edge (face) of the cathode rests. Here, component 1 comes to rest on the plate 17 * Then centering pins are inserted into the holes 2 inserted and on the metal insert plates of the plate 17 welded on. According to this, the lesson from the electrical

bloeks placed with respect to the axis of the mounting block cylinder , i.e. the electrolysers are after they have been attached the centering pins are identical to each other and also to the mounting block.

The assembly of the cathode bell and the diaphragm is carried out on the assembly block as follows: On the cylinder 18 (Fig. 5d), the diaphragm 21 (Fig. 5h) is pushed on so that that its upper face is below the upper edge (the upper face) of the cylinder. then the shoes 9 (Fig. 3) are mounted. The cathode bell 19 (FIG. 5e) provided with hanging rods is placed on the shoes 9 of the cylinder 18 placed. Frame 22 (Fig. 5k) is placed on plate 17 and the hanging rods are attached to it Cathode bell 19 attached, to which in turn diaphragm 21 (Fig. 5h) is attached.

The lifting and placing device 23 (Fig. 5 ζ) is lowered in such a way that the centering pins 3 of the mounting block (Fig. 5d) engage in the bores of the centering claws of the device.

Then the frame becomes the lifting and positioning device connected to the frame 22 (Fig. 5k) and brought the entire assembly to the electrolyzer and placed on it.

The lifting and placing device 23 (Fig. 5JÜ) is so

placed on the electrolyser that in the holes of their

10 981 7/07 14

Centering claws engage the pin 3. After that, the The bell with the diaphragm is lowered into the electrolyser, the lifting and placing device is detached from the bell removed from the electrolyzer. Finally collectors 24 and 25 (Fig. 5n) for collecting chlorine and sodium are installed

F Example II.

The assembly jig for electrolysers contains component 26 (Fig, 5: and 7), which is made in the form of intersecting beams from * which, in order to increase their rigidity, are connected to a frame and bores 27 for the ones mentioned in the first example Have centering pins. Component 1 is welded to the support 28, which in turn is rigidly connected to the element, which is designed in the form of four pipe pieces 29 attached to the common flange 30. The number of pipe sections corresponds to the number of electrolyzer cathodes. The outside diameter of each pipe section is 0.1 mm smaller than the inside diameter of each electrolyzer electrode, while the inside diameter of the flange is 3 ° and 0.1 mm larger than the outside diameter of the electrode model of the shoes 9 (Fig. 3) of the Morita block.

Assembling the electrolyzer described in the second example will be similar to assembling the one in the first Example described electrolyser carried out. The one

109 8T77Ü714

Efie zige difference is that pipe pieces are placed accordingly on the cathodes and that a mounting block (not shown in the drawing) with models of these four cathodes is available.

Since the same assembly jig is used for all Eiektrolyseure a series which Z _e are ntrierzapfen mounted identical, but this allows, with one and the same lifting and placing device bell and diaphragme be mounted exactly in the intermediate electrode space and coaxially with the anode and cathode surface.

The centering process described is based on one or more electrolyzer electrodes, but it can also include the same success can be carried out with respect to the anode or the anodes of the electrolyzer.
